Wood central-heating stove La Nordica Sierra 16 – 15.4 kW

The La Nordica Sierra.16 is a large wood-fired central-heating stove with an open vessel and closed circuit, designed as the beating heart of your heating installation: connected to your central-heating system it feeds the radiators and produces domestic hot water, while the 51-litre oven also lets you cook. Of the rated output of 15.4 kW, 10.2 kW is delivered to the water. It heats volumes of up to 442 m³ at an efficiency of 86% (76% seasonal efficiency).

A touch display controls every function: water level for the bain-marie, oven light, system water temperature, domestic hot-water temperature, system pump, 3-way valve, AUX pump, AUX generator and acoustic alarm signalling. The standard hydraulic kit includes a coil for the heating circuit and the sanitary circuit, a control unit with anti-freeze and anti-blocking functions, an electronic circulator, a non-return valve, an automatic air vent, a sanitary flow switch, a level switch, a magnesium anode and a temperature probe.

The front, frame and doors are in enamelled cast iron, the sides in enamelled steel, finished in a sleek anthracite black. A stainless-steel lid with a polished cast-iron plate gives access to the coils and the water inlet, and separate access points for the technical compartment and ash pan simplify maintenance. The flue outlet has a diameter of Ø150 mm and can be connected at the top or the rear.
